Description

Process for sliver treatment in combing, can rack for combing machines and machine in ICimmerei

The invention relates to a method for sliver treatment in the combing, a can frame for combing machines and a machine in the combing.

Comb preparation machines have always been supplied with round cans for processing sliver. At the exit of the preparation machine, the fiber material produced is wound up on a winder, which is then conveyed to a comber. The fiber material unrolled from the roll is combed in the comber and leaves the machine in the form of a sliver, which is placed in a round can, so that it can then be fed to a further processing machine, in particular a draw frame.

A disadvantage of the prior art mentioned is that the procedure described is extensive and also not optimal from an economic point of view.

It is an object of the present invention to improve the processing and processing of sliver in the combing.

This object is achieved in a method of the type mentioned at the beginning by the features of claim 1, in a can frame by the features of claim 10 and in a combing machine by the features of claim 18.

In the method according to the invention, flat combs are delivered to a combing preparation machine or a combing machine, in which sliver is placed in a loop or ring shape and which is drawn off for processing in the machine in question. The invention also encompasses the loop-shaped or ring-shaped depositing of produced sliver in flat cans at the exit of a combing machine or a combing machine. The proposal to use flat cans has the advantage that the space around the combing machine can be optimally used. The previous use of flat cans in other Other textile machines - for example draw frames and rotor spinning machines - are expanded according to the invention to machines in the combing shop. Since the space for the material template can be better used, longer runtimes are possible until the next can change. Due to the loop-shaped position of the slivers in the cans, on the one hand a high degree of can filling can be achieved and on the other hand an orderly band deposit and orderly band take-off can be carried out.

In the can rack according to the invention assigned to the combing machine (also referred to as infeed table), the supply cans are preferably set up next to one another, the cans with their long sides facing one another and thus forming a series of aligned supply cans.

A row of reserve cans is preferably set up or can be set up behind this row. It is therefore possible to quickly switch from empty supply cans to filled reserve cans, which only have to be moved a short distance to get to the original position. The can change times are kept short accordingly.

As an alternative to a row of reserve cans, a second row of storage cans can be set up behind the (first) row of storage cans. After the cans in the first row have run empty, sliver from cans in the second row is presented to the machine without the cans in the second row being moved to the position of the cans in the first row. During the withdrawal from the cans of the second row, the empty cans of the first row are exchanged for filled cans. The same applies analogously to the cans in the second row if they are empty.

An operating path can be provided between the first row and the second row of storage cans or between the first row of storage cans and the row of reserve cans.

The can frame is advantageously designed in such a way that an exchange of empty for full presentation cans on the end faces of the first and / or the second Series of supply cans and / or the series of reserve cans can be made. For this purpose, the cans are shifted in their transverse direction in order to be picked up or delivered preferably by a — preferably driverless — transport vehicle. The cans can be moved either individually or in blocks.

In an alternative, empty flat cans are replaced by filled flat cans by shifting in their longitudinal direction. Here, the cans to be exchanged are preferably again in a row and are exchanged individually or in blocks. The exchange can be carried out - if there is enough space - in the empty space between the row of empty cans and the combing machine or from the side of the empty cans facing away from the combing machine. A transport vehicle is in turn advantageously used to transport the cans, change cans and remove cans.

In a special embodiment, full or full supply cans, which are set up in working positions for the current take-off of the slivers, alternate with empty or full supply cans, which are set up in a reserve position after the take-off has taken place or for later take-off, and form together a row of cans in which the cans are arranged with their longitudinal sides facing each other. In the case of such a can set-up, the two different can positions are preferably used alternately, so that at one point in time a can position represents a working position and at a later point in time becomes a reserve position. In this context, it makes sense that pulling devices for pulling off the fiber slivers are preferably designed and arranged on the can frame in such a way that the fiber slivers are alternately drawn off from two adjacent jugs and can be fed to the drafting units.

In an advantageous embodiment, take-off and / or deflection devices are arranged above the feed cans in such a way that the slivers can be pulled off in the middle. Thus, short transport routes for the sliver can be realized and there are no additional deflections, which adversely affect the Impact band structure, since the band is slightly compressed in the area of the respective deflection and the twists in the band have no possibility to dissolve.

Another aspect of the invention is a combing machine, which is designed for the delivery of flat cans and for the removal and processing of sliver stored in the form of slivers in these storage cans and / or for the delivery of storage cans which are essentially rectangular in cross section and for the slotted storage of sliver in these storage cans ,

In one embodiment, the combing machine according to the invention is designed in such a way that the storage cans which are essentially rectangular in cross section can be conveyed under the turntable of the belt storage device. This means that the flat can leaves the can filling station in a different way compared to its request. Such delivery and removal is also possible, but extends the pitch change time.

The funding mentioned can be a linear funding in the longitudinal direction of the can. In an alternative, the feeding direction of the can encloses an angle with the conveying direction, preferably a right angle. Cross-conveying is also possible.

The mentioned funding options can be realized both with a combing preparation machine and with a combing machine.

If the machine according to the invention is designed as a combing machine, it preferably has a plurality of combing heads lying next to one another. With such a design, at least two rectangular feed cans are preferably assigned to each combing head, from which feed ribbons stored in loops are pulled off for simultaneous combing. If the textile machine according to the invention is designed as a combing preparation machine with at least one drafting system, in a particularly preferred embodiment this drafting system is arranged higher than the upper edge of the flat supply cans. If the drafting system is also inclined upwards in the direction of draft, fiber slivers can be drawn into the drafting system from below. In the usual combing preparation machines, for example the UNILAP from Rieter, the card slivers to be presented are guided to the drafting system via a transfer of an operating aisle and several guide rollers. The slivers run from above into the drafting system, which is arranged essentially at the level of the upper edge of the supply cans. By means of the embodiment according to the invention described, complex constructions can be avoided, such as the transfer of the operating aisle. This also results in short belt transport routes from the can to the drafting system. Likewise, the risk of breakage can be reduced by the belt guide, since only a few deflections are imposed on the belts. In a special variant in this regard, intermediate guides and / or deflections for the fiber slivers on their way from the supply cans into the drafting system are even completely dispensed with.

The described arrangement of a drafting device running from bottom to top in a combing preparation machine is in principle independent of the type of can used and represents a separate invention in itself.

It is particularly preferable for the at least one drafting unit of the combing preparation machine to be fed from both sides of the machine, advantageously in at least one row along the machine. If, for example, six fiber slivers are to be stretched per drafting system (duplication six times), three supply cans to the left of the drafting system and three supply cans to the right of the drafting system can be delivered.

Advantageous developments of the invention are characterized by the features of the subclaims. The invention is explained in more detail below with reference to the figures. Show it:

FIG. 6 shows a top view of a schematically illustrated combing preparation machine with a third possibility of setting up presentation and reserve cans;

Figure 7 is a plan view of a schematically illustrated combing machine with a fourth possibility of setting up feeding cans, and

Figure 8 is a plan view of a combing machine shown schematically with delivered flat cans.

FIG. 1 schematically shows a combing preparation machine 1 seen from the storage side. On both sides of the combing preparation machine 1, supply cans 20 with an essentially rectangular cross section (flat cans) are set up, in which sliver 30 from a card in the form of loops or Wrestling is filed. The flat cans with fiber tapes can also come from a section which is connected downstream of the card. Several feed cans 20 on each side of the combing preparation machine 1 stand along the long side (see FIGS. 2-7). A deflection roller 4 is arranged above each can 20, which are attached to an infeed table or can frame 7 (attachment shown only schematically). As an alternative or in addition, take-off rollers are provided for one or more slivers. Such an arrangement enables tape to be drawn off above and in the middle of each feed can 20. Due to the central withdrawal from the can, the transport path of the sliver can be kept as short as possible, so that no additional deflections are required. It is advantageous here that the tape can be deposited on the part of the previous machine into the feed cans 20 without the occurrence of tape rotators. Such tape rotors, which arise when the tape is deposited in round cans, would have a disadvantageous effect on the quality of the cotton web to be formed or of the sliver to be formed.

The central pull shown also has the advantage that the flat cans 20 provided do not require a floor which is movable in height and which is moved upwards during the emptying of the can 20. Such can bottom lifting devices are otherwise realized by means of springs in the can or by external lifting means (mechanical, magnetic, etc.).

An additional floor, a rolling floor or slide rails can be arranged below the supply cans 20, which are identified in the present case by reference number 2. Rollers or slide rails facilitate the delivery and removal of filled or emptied supply cans 20 (see double arrows).

The embodiments according to FIGS. 2 and 3 differ in particular from the one according to FIG. 1 in that the fiber slivers 30 drawn from the supply cans 20 run upwards into two drafting units 3a, 3b of the combing preparation machine 1 after being deflected by deflecting rollers 4. In contrast to the state of the art, the two drafting units 3a, 3b are inclined upwards in the direction of belt travel. The from the slivers 30 from the can 20 to The drafting system 3a, 3b is very short in this embodiment. In addition, the slivers 30 undergo only a slight deflection before they enter the drafting system 3a, 3b, so that the risk of sliver breakage is very low overall. Guide elements for the precise introduction of the fiber slivers 30 shortly before the drafting unit 3a, 3b are not shown for the sake of clarity.

The two embodiments according to FIGS. 2 and 3 differ from one another essentially in that a winding head 6 is provided in that of FIG. 2 for winding the stretched nonwoven into a cotton web, while in that of FIG. 2 there is a sliver storage with the help of a turntable 8 is. In both embodiments, each drafting unit 3a, 3b is assigned six supply cans 20, which are divided into two groups of three cans 20 on each side of a drafting unit 3. In FIG. 3, a feeding can 20 indicates that the sliver 30 is placed in a loop shape therein; this is not shown in more detail in the case of the other can 20 as in FIG. 2. For reasons of clarity, no rolling floor, slide rails or the like is shown below the supply cans 20 in FIGS. 2 and 3.

From the outside drafting system 3a, the resulting nonwoven fabric - after deflection - is guided in a straight path over the nonwoven table 5 and, at the exit of the inside drafting device 3b, is superimposed with the nonwoven fabric produced there. The two nonwovens are compressed by means of calender rolls (not shown).

In the embodiment according to FIG. 2, the resulting wadding is rolled up into a wrap in the winding head 6, the wadding web subsequently being able to be presented directly to a subsequent comber.

In the embodiment of FIG. 3, in which the nonwoven fabric produced in the drafting unit 3a or 3b is shown in broken lines or dotted lines, the two nonwovens are drawn into a downstream drafting unit 3c and the fiber material 31 produced in the drafting unit 3c - after deduction by any provided Calender rolls - by means of the turntable 8, placed in loops or rings in a substantially rectangular storage can 22, which changes in the longitudinal direction (see double arrow), similar to the knew sliver storage in rectangular cans on cards or draw frames. The sliver 31 in the storage can 22 can then be fed to a comber.

In an alternative, which is not shown in any more detail, no additional drafting arrangement 3c is provided. If the two superposed nonwovens from the drafting units 3a, 3b have only a relatively small mass, such a drafting arrangement can be dispensed with, so that only one pair of calender whales is sufficient to feed the resulting sliver 31 to the turntable 8 for storage in the flat can 22.

The storage can 22 according to FIG. 3 can be transported in the imaginary line in the longitudinal direction from a waiting position into the filling position below the rotary plate 8 and then further in a straight line. In an alternative, the storage can 22 is transported in its transverse direction into the filling position and is transported away at right angles to it. The opposite way is also possible, i.e. Transport in the longitudinal direction and transport in the transverse direction.

In a variant not shown in detail, the fiber slivers 30 are inserted directly from the cans 20 into the drafting system 3a or 3b, without deflecting rollers 4 or other intermediate guides being arranged above the supply cans 20.

FIGS. 4-7 show various advantageous possibilities for the presentation of cans and for the exchange of empty presentation cans 20 for filled reserve cans 21 in a combing preparation machine 1 with a maximum of 28 times doubling in supervision. The machine 1 again has two drafting units 3a, 3b and a downstream storage 9 (either with a winding head 6 or a turntable 8, cf. FIGS. 2 and 3). All of the exemplary embodiments have in common that the cans 20, 21 are arranged symmetrically with respect to the longitudinal axis of the machine. For the sake of clarity, no can racks are shown in FIGS. 4-7.

In the exemplary embodiment according to FIG. 4, a row 40 of feed cans 20 which are essentially rectangular in cross section is fed to both sides of the combing preparation machine 1. The two drafting units 3a, 3b are here the same number of feed cans 20 are assigned to the left and right of the machine 1, so that - like in the machines shown in FIGS. 1-3 - fiber slivers 30 are fed to the combing machine 1 from both sides. The feed cans 20 closest to the drafting units 3a, 3b are assigned to the left and right of the machine 1. In the case of FIGS. 4-6, the seven upper supply cans 20 are assigned to the drafting system 3a and the seven lower supply cans 21 are assigned to the drafting system 3b. The fiber slivers are drawn off from all 28 feed cans 20 at the maximum 28 times doubling (the fiber slivers are not shown for the sake of clarity).

On the side of the supply cans 20 facing away from the combing preparation machine 1, transport vehicles 50 can be moved along the machine 1 in the direction of the vertical double arrows, which are advantageously designed to be driverless to increase the degree of automation. The transport vehicles 50 deliver reserve cans 21 filled with sliver-like sliver 30 and change them in known ones

Way by moving the template or reserve cans 20, 21 in their longitudinal direction (see horizontal double arrows). The cans 20, 21 can be replaced individually, but is advantageously carried out in a block. In the exemplary embodiments shown in FIGS. 4 and 5, filled cans 21 are placed on three adjacent parking spaces of the vehicle 50, while the other three parking spaces 51 are free to accommodate three empty storage cans 20 in the block. The vehicle 50 is then moved by three can widths in order to move the three filled cans 21 to the three vacant parking spaces of the can row 40 on the machine 1 in the block.

The advantages of setting up the can or changing the can according to FIG. 4 are, in particular, that only a small space is required for the supply cans 20. A single transport vehicle 50 is also sufficient for each row 40 and possibly also for both rows 40. In addition, the belt travel distances from the feed cans 20 to the respective drafting units 3a and 3b are short. In the exemplary embodiment according to FIG. 5, the rectangular flat cans 20 are set up in four blocks 42, two blocks 42 separated from the machine 1 each being assigned to a drafting system 3. The cans 20 can in turn be replaced individually or in blocks of three cans in the present case, the exchange taking place essentially analogously to that according to FIG. 4. The advantages of this exemplary embodiment correspond to those described with reference to FIG. 4. In addition, good operability is ensured by the block arrangement of the cans 20.

According to the variant shown in FIG. 6, two rows of cans 40, 41 are arranged on each machine side. The supply cans 20 are set up in the respective can row 40 near the machine, while the can rows 41 remote from the machine serve to accommodate the reserve cans 21. In the present case, the can delivery and removal is carried out at the end of the machine that is far away from the tray, in that the empty canons 20 are moved blockwise in their transverse direction onto a first transport vehicle 50a. Then 41 full cans 21 are moved from the reserve row 41 in the longitudinal direction of the cans to the empty places of the original can row 40. In this case, the row of reserve cans 41 had previously been completely ordered with the reserve cans 21 filled with the aid of an expediently second vehicle 50b.

To transport reserve cans 21 from row 41 into row 40, a filled reserve can 21, for example, can only be moved to the opposite, free parking space of row of original cans 40 at the machine end near the shelf. Subsequently, the supply cans 20 are displaced by one can width in the direction of the first vehicle 50a, while the reserve cans 21 are simultaneously displaced by one can width in the opposite direction, so that the next filled reserve can 21 at the end of the machine near the storage area faces the empty parking space for a supply can 20 and the process can be repeated until all reserve cans 21 are in line 40.

In an alternative, for example, all emptied supply cans 20 are first removed by means of one or more vehicles 50a and all reserve cans 21 moved by longitudinal displacement from its reserve position to the working position in the original can row 40 (indicated by the dashed, horizontal arrows). Subsequently, all the parking spaces of the row of reserve cans 41 are filled with filled reserve cans 21 with the help of one (or one after the other of several vehicles) 50b.

Since the transport vehicles 50a, 50b in the selected exemplary embodiments have fewer parking spaces than the template and reserve can rows 40, 41, the cans 20, 21 in the corresponding rows are each - in the illustrated case - in a block of six cans 20, 21 shifted to or from the vehicle 50a or 50b. This is symbolized by the vertical arrows inside the vehicles 50a, 50b. The vehicles 50a, 50b can be moved on the machine 1 in accordance with the horizontal double arrows assigned to them.

For the can transport within the rows 40, 41, driven means of transport or passive pushing aids are advantageously provided under the cans 20 and 21, for example roller conveyors, conveyor belts, slide rails or the like, as is the general state of the art. The transfer to or from a vehicle 50a, 50b can also take place in a known manner, for example by means of pneumatic cylinders or the like.

In the exemplary embodiment according to FIG. 7, in a row 44 along the combing preparation machine 1 with feed cans 20 there are alternate working positions 45 and (here shown empty) reserve positions 46 which, in the present case from the outside by means of a transport vehicle 50 (only one is shown) ) when the cans are changed, swap their positions, ie the previous work position becomes the reserve position and vice versa. The reserve cans 21 delivered in the rows 44 serve - after an preferably adjacent feed can has run dry - thus subsequently as feed cans. The draw-off devices, which are not shown in any more detail, are designed and arranged in such a way that the fiber slivers are alternately drawn off from the supply cans 20 located next to one another and fed to the drafting units 3a, 3b. This results in short downtimes for the submission Change or can change. The reserve positions 46 can also be loaded with the reserve cans 21 to be emptied even during the emptying of the original cans 20 in the working positions 45.

FIG. 8 shows a combing machine 10 with six combing heads 12 lying next to one another in a top view and schematically. Each combing head 12 is supplied with two cross-sectionally substantially rectangular cans 24 placed in a row 48, from which slivers 32 (shown in the case of a can) are taken off in the form of loops. For this purpose, a can frame 17 with deflection rollers 14 runs above the supply cans 24 (cf. FIGS. 2, 3); any existing take-off rollers are not shown.

The slivers 32 are combed in the combing heads 12 and guided over the sliver table 15 to a drafting system 13, in which the slivers 32 are combined to form a single sliver 33. In the subsequent band storage 19 (see dashed arrow 33), a turntable 18 places the sliver 33 produced in the form of a loop in a storage can 26, which in the present case is designed as a flat can. In the exemplary embodiment shown, the storage can 26 is transported from the side of the storage cans 20 to the filling position and, after filling, is transported to the other machine side. As an alternative, it is possible, for example, to transport the can 26 to be filled in the transverse or longitudinal displacement to the filling position in order to remove it after filling at a right angle to the direction of transport.

A row 49 of reserve cans 25 of the same number is placed behind the row 48 of supply cans 24. After the supply cans 20 have run dry, they are moved in the block along the machine 1 in the direction of the horizontal arrow | transported away, while the reserve cans 25 are moved block by block in the direction of the vertical arrows f ₂ to the position of the template cans 24. In this embodiment, very few stoppages are advantageously caused when the cans are changed and adjusted. 8, the use of one or more transport vehicles for the transport of filled reserve cans 25 as well as the removal of empty supply cans 24 and possibly filled storage cans 26 is also possible.
